On July 21st in 2005, People's Bank of China (PBOC) turned the currency peg against the U.S. dollar into managed currency system based on a basket of unnamed currencies under China's exchanged rate regime. This change means that China's enterprises are not free from currency fluctuations. The purpose of this study is to analyze the relations between Renminbi fluctuations in the floating exchange rate and financial results of venture companies. The process and outcomes of this study are as follows, First, in order to measure the financial results of venture companies, I choose venture companies in Shandong Province listed on the Shanghai Stock Exchange (SSE) at random and several quarter financial sheets according to safety ratios, profitability ratios, growth ratios, activity ratios. Second, I arrange the daily Renminbi exchange rate data announced from July 21st, 2005 to December 31st, 2008 by PBOC into the quarterly data. Third, in order to confirm the relations between Renminbi fluctuations and financial results of venture companies, I carry out Pearson's correlation analysis. As a result, the revaluation of the Chinese Renminbi has weakly negative effects on debt ratio, total assets turnover ratio and equity turnover ratio in statistics. But the revaluation of the Chinese Renminbi is not related to other financial index in statistics. The result of this study is that the revaluation of the Chinese Renminbi has little influence on the export and import of Chinese venture companies and certifies the fact that Chinese venture companies have much foreign currency assets. In addition to avoid the currency exposure risk, this study shows the effective method about currency exposure risk which adjusts proportion of Renminbi to foreign currency.

This research was conducted in order to examine the effect of tooth brushing room M elementary school in Changwon-city and to provide foundation data for effective project operation afterwards. The subjects were 347 students at the M elementary school where the tooth brushing room was being taught. The control group is 289 students at J elementary school where the tooth brushing room was not being taught. Research and analysis were carried out with structured survey and examination of decayed, missing, filled teeth (DMFT) index, decayed, missing, filled tooth surface (DMFS) index and O'leary index. The data was analysed by IBM SPSS Statistics ver. 19.0 program and the result is as follows: Depends on the tooth brushing room there was difference in statistical significance in filling teeth, sealant tooth surface, filling tooth surface, missing tooth surface, DMFS, O'leary index between the subject and control group. The less the frequency of brushing, the higher the DMFT index. Negative correlation was statistically significant. With incorrect brushing method, the less the frequency, the higher the DMFS index, Negative correlation was statistically significant. When the tooth brushing room was being implemented, O'leary index became low, negative correlation was statistically significant. As a result, in order to continue the effective operation of tooth brushing room, constant supervision and monitoring on students should be acutely needed by a principal, a school nurse and teachers in charge. Also together with a systemized cooperation between a health center and a nearby university's related majors departments, the research proposes to execute constant oral health education and to expand the implementation project of the tooth brushing room at nearby elementary schools.

In order to get the fundamental information that could be useful to judge the potentiality of occurrence of rapid shallow landslide in the objective slope, factors selected on Jinhae regions in Korea, where many landslides were caused by heavy rainfall of daily 465 mm and hourly 52mm in August 1979, was carried out through the multiple statistics of quantification method (II) by the electronic computer. The net system with $2{\times}2cm$ unit mesh was overlayed with the contour map of scale 1:5000. 74 meshes of landslides and 119 meshes of non-landslide were sampled out to survey the state of vegetative cover and geomorphological conditions, those were divided into 6 items arid 27 categories. As a result, main factors that would lead to landslide were shown in order of vegetation, slope type, slope position, slope, aspect and numbers of stream. Particularly, coniferous forest of 10 years old, concave slope and foot of mountain were main factors making slope instability. On the contrary, coniferous forest of 20-30 years old, deciduous forest, convex slope and summit contributed to the stable against Landslide. The boundary value between two groups of existence and none of landslides was -0.123, and its prediction was 72%. It was well predicted to divide into two groups of them.

The study was conducted to identify the effects of life stress and anger expression in college students on suicidal ideation. In order to get the data by self-report questionnaires, 219 subject were selected from 14th of November to 6th of December, 2014. The collected data were analyzed using SPSS/Win 18.0 and descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and hierarchical regression analysis. The findings reveal that suicidal ideation of college students was low which is average score $5.74{\pm}6.38$(possible range 0~38). This study determined that suicidal ideation is positive correlated with life stress and anger expression(anger-out, anger-in). The extent of anger-out, anger-in, family relationship and major satisfaction was a significant predictor of suicidal ideation and accounted for 24% of the explanation of suicidal ideation of college students. Base on the outcomes of this study, designing an intervention program that emphasizes stress and anger management in order to decrease suicidal ideation.

As medical treatment is developing with technology, the men's average life expectancy is extended. Therefore, primary medical care becomes emphasized in order to reduce the medical expenses in the long term by satisfying individual's life being healthy. The date for this thesis was collected from January 2011 to June 2011. 889 patients who visited the university hospital emergency room and hospitalized in internal medicine, were picked as the research subjects and they were targeted to be recorded the distribution of chief complaint and principal diagnosis of the patients. Also, this record was used to apply to the standard Classification of Diseases(as known as ICD) and the method of detailed classification of the primary medical care(as known as ICPC) to compare each other. In order to analysis, frequency analysis was used to see vital statistics and the cross tabulations were used to see the distribution of chief complaint according to ICD and ICPC. Results of the research were Abdominal pain(17.7%), Dyspnea(13.5%), Fever (12.5%), and Haematemesis (9.8%), and those symptoms represented the 54.5% of overall chief complaints that is treated in primary care. Therefore, it is acceptable to use the classification of the primary medical care at doc-in-a-box. Also, in case of diagnosis of abdominal pain, it is classified to R10 in ICD and 116 patients(18.7%) belonged to it, but according to ICPC, it is subdivided to Epigastric(11.5%) and General(5.8%). ICPC classification, which is focused to primary medical care is more detailed than ICD classification. Because the data that is collected for this thesis is from only one hospital, it is hard to represent to all the cases, but ICPC in emergency medical care, it has more classification available and it can subdivide the patients effectively, so it is meaningful.

Assessment of vulnerability of water use to climate change include a variety of climate change scenarios. However, in most future vulnerability studies, only the climate change scenarios are used and not the future scenarios of social and economic indicators. Therefore, in this study, we applied the Representative Concentration Pathway (RCP) climate change scenario and Shared Socioeconomic reference Pathway (SSP) developed by IPCC to reflect the future. We selected indicators for estimating the vulnerability of water use, and indices were integrated with a multi-criteria decision making approach - Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The indicator data utilized national statistics and reports, social and economic scenarios, and simulated results from the Soil and Water Assessment Tool (SWAT) model which reflects climate change scenario. Finally, we derived the rankings of water use vulnerability for the short-term future (2020) and mid-term future (2050) within the Han River watershed. Generally, considering climate change alone and considering climate change plus social and economic changes showed a similar spatial distribution. In the future scenarios, the watershed rankings were similar, but showed differences with SSP scenario in some watersheds. Therefore, considering social and economic changes is expected to contribute to more effective responses to climate change.

Various innovation theories, such as innovation system, innovation cluster, triple helix model, are different in their focus. However they all emphasize the interaction between innovation actors in order to generate, diffuse, and appropriate technological innovations successfully. This study analyzes how the interaction of innovation actors in Daedeok Innopolis has been changed since the introduction of innovation cluster policy like the designation of Daedeok Innopolis. Based on the analysis of survey data, Innopolis statistics, and patent joint-application data, we come to the conclusions that the Daedeok Innopolis has characteristics of multi-level governance structure, in which innovation cluster, i.e. Daedeok Innopolis, regional innovation system, and national innovation system directly overlap under the framework of innovation system. In addition, from the perspectives of triple helix model, we are able to verify that the inter-domain interactions between innovation actors, such as tri-lateral network, have been constantly increased in the Daedeok Innopolis. Based on our analysis, we identify some policy suggestions in order to strengthen the competitiveness of the Daedeok Innopolis as well as other innovation clusters in Korea. First, the network activities between innovation actors within innovation cluster should be strengthened based on the geographical accessibility. Second, private intermediate organizations should be established and their roles should be extended. Third, the entrepreneurial activities of universities within innovation cluster should be strengthened. In other words, the roles of universities within the Innopolis should be activated. Finally, the government should provide relevant policy supports to activate the interactions between innovation actors within innovation cluster.

This study analyzed the effects of small business CEO's competencies type on business performance. For this purpose, 4 independent variables(strategic, marketing, management and network competencies) and 2 dependent variables(financial and non-financial performance) were used. 220 data were collected from the field survey questionnaires administered to a convenience sample of small business CEO. For hypothesis testing, the IBM SPSS Statistics 24.0 was used. Frequency analysis, exploratory factor analysis, correlation analysis, and hierarchical regression analysis were conducted. Empirical studies showed as follows. First, this study showed that the four competencies were significant to financial performance and the three competencies(except management competencies) were significant to non-financial performance. The higher small business CEO's competencies, the more likely it affects both the financial and non-financial performance of the company. Second, effects of small business CEO's competencies on financial performance were analyzed in order of network competencies > management competencies > strategic competencies > marketing competencies. Third, effects of small business CEO's competencies on non-financial performance were analyzed in order of network competencies > marketing competencies > strategic competencies. These findings had some implications. In academia, the impact forces of 4 small business CEO's competencies were analyzed for the first time. In practices, successful start-ups or sustainable management requires an interest in the active enhancement of small business CEO's competencies.
